Rampion 2 is a proposed expansion of the Rampion Offshore Wind Farm located in the English Channel off the Sussex coast. The offshore area of search being reviewed for development of the new wind farm is adjacent to Rampion.
The Rampion 2 project design works are ongoing. Proposals are being developed so that consent for development may be sought in late 2021.
This page gives you a high level introduction to the project and how offshore wind farms work in general. The latest project specific proposals are available to view in our first virtual exhibition on Rampion 2 plans.
Explore the interactive map to see the broad onshore and offshore area of search we are investigating to identify the best location for the wind farm and associated electrical infrastructure. Use the information icons to find out more about the project.
The broad areas of search presented on the map were defined in July 2020. The plans are being refined over time. Emerging details and an explanation of the key constraints that define the design are presented in our first virtual exhibition on Rampion 2 plans.
A typical offshore wind farm will be made up of an array of offshore wind turbines that are fixed to the seabed. The wind turbines feed green power into offshore substations via underwater cables.
Offshore substations collect and moderate the voltage of electricity. Stepped up to a high voltage, electricity can travel long distances very efficiently. These substations are typically housed on platforms near to the wind turbines.
Underwater export cables transmit the electricity to a landfall location where the offshore cables are jointed to the onshore cables. The cables can be drilled under a beach. From there, the cables can be run underground through to an onshore substation. The role of an onshore substation is to transform the electricity to flow at the correct voltage and frequency into the nation’s transmission system.
Work is ongoing to establish:
The final scope and design of project which we will ultimately prepare a development consent application for, is yet to be fully determined. It will be shaped by technical, environmental and economic factors alongside consultation feedback from statutory consultees, key stakeholders and the local community.
The design options for Rampion 2 sit within a maximum envelope that has been established for the purpose of assessing the maximum potential impacts of the project. These key statistics for Rampion 2 are taken from our Scoping Report.
At least 13km off the Sussex coast. This is the same minimum distance from shore as Rampion.
Up to 116 turbines, with maximum 325m tip height above LAT (Lowest Astronomical Tide)
– technology has been evolving fast and state of the art turbines are much more powerful than those used for Rampion 1!
Up to 1200 MW of electricity able to power 1m+ homes equivalent.
Route for a 36-37km underground cable is being explored from Climping on the coast to Bolney in mid Sussex. We submitted an application for a connection to National Grid, as the owner and operator of the UK’s electricity transmission system. Following their assessments they have offered Rampion 2 a connection to the Bolney National Grid Substation. This existing substation can accommodate the large output of electricity that Rampion 2 could supply. We will seek the route with the least disturbance to local ecology, geographical features and sea users.
A new onshore substation is needed in the vicinity of Bolney to control the electricity flow onto the national transmission system. A range of sites, up to 5km away from Bolney were assessed leading to a current shortlist of 3 candidate sites.
